I am not be cocktails-on-the-beach-guys, beer would be sufficient for me ;-)
This guy has some nice ideas about a cooler. There is a potential market for this, and prices may decrease over a while.
If I would live in the US, have some kids and doing outdoor-activities with hoards of kids every weekend, this might be a good solution. I would pay $180.00 for a kickstarter-cooler.
